Binn Mhór (Irish for "great peak")[2] is one of the Maumturk Mountains of Connemara in County Galway, Ireland.

[4][5] Binn Mhór is on the southern side of the pass of Máméan, on a small massif that includes Mullach Glas (661 metres (2,169 ft)) and Corcogemore (609 metres (1,998 ft));[6] this massif is at the far southeastern sector of the long north-west to south-east spine of the Maumturks.

[5][7] Irish academic Paul Tempan records that Binn Mhór has also been called "Shannakeala".

[6] Máméan has been a site of pilgrimage dedicated to Saint Patrick since the 5th century, and several historical items are dug into the lower southerly slopes of Binn Chaonaigh (633 metres (2,077 ft)), on the northern side of Máméan, including a holy well, a cleft in the rock known as Saint Patrick's Bed (Irish: Leaba Phádraig) where the saint reputedly slept, a circle of stones for the Stations of the Cross, and a Mass Rock (Irish: Carraig an Aifrinn).

[6] Binn Mhór is also climbed as part of the Maamturks Challenge, a 25-kilometre 10–12 hour walk over the full Maumturks range (from Maam Cross to Leenaun), which is considered one of the "great classic ridge-walks of Ireland",[7][11] but of "extreme grade" due to the circa 7,600 feet of total ascent.
